Can't find PARTUUID=eb55478c-02

[ssdeol]

Hi friends,

please suggest me how i can fix it. in my cmdline.txt

details are as follows:
dwc_otg.lpm_enable=0 console=ttyAMA0,115200 console=tty1 root=/dev/mmcblk0p2 rootfstype=ext4 elevator=deadline rootwait init=/bin/sh

im tring to reset the lost root passwd but without putting this command i can't do this.

when ever i try
mount -o remount,rw /

i got error
Can't find PARTUUID=eb55478c-02

my blkid is as follows:
/dev/mmcblk0p1: LABEL="boot" UUID="95E0-9AC4" TYPE="vfat"
/dev/mmcblk0p2: UUID="b105f9a8-f450-4976-8ac8-69053f57bab4" TYPE="ext4"

/etc/fstab
contains
PARTUUID=eb55478c-01 /boot vfat defaults
PARTUUID=eb55478c-02 / ext4 defaults

The quick fix is to do the same thing you did for cmdline.txt to fstab. Replace PARTUUID=blah with /dev/mmcblk0pX

An alternative is to replace PARTUUID=foo with UUID=bar where bar is the UUID returned by blkid.

I experienced exactly the same problem, but it was solved by changing PARTUUID=blah to /dev/mmcblk0P1 and P2.
The /etc/fstab now looks like this:

Code: Select all

proc                   /proc           proc    defaults          0       0
#PARTUUID=bc6dfc1a-01  /boot           vfat    defaults          0       2
/dev/mmcblk0p1         /boot           vfat    defaults          0       2
#PARTUUID=bc6dfc1a-02  /               ext4    defaults,noatime  0       1
/dev/mmcblk0p2         /               ext4    defaults,noatime  0       1
# a swapfile is not a swap partition, no line here
#   use  dphys-swapfile swap[on|off]  for that

If I could, ShiftPlusOne's answer would be upvoted

I have the same problem...
Forgot my passwd for my raspberry zero w and want now to reset it. At the Moment a am stuck at the Error cant find partuuid... by typing in mount -o remount,rw/ .
I‘m now not realy shure how to fix the fstab file on my Pi. I tryed to get more information about dev/mmcblk0, dev/mmcblk0p1 and dev/mmcblk0p2.
But couldnt open them with nano.
I know about the mount -o remount,rw / comment taht it is used to over write the mode of a file/diractory to read and write.
And that can I use to over write the mode of a file that allows me to change passwd without authentification token error.
But I‘m realy not shure, if my train of thought is correct.
If you have a idea I would be happy....
Sorry for my spelling

Just for future pp, try remounting as follows as well:

Code: Select all

sudo mount -o remount,rw /dev/mmcblk0p2 /

I am running Raspbian Buster on a Raspberry PI 2.

`lsblk` returned nothing, but `mount` did.

I used `mount -o remount,rw /dev/root /`

Since `/bin/bash` exists in the root prompt, it's probably ok to use `init=/bin/bash`.
